COMBINATION-LOCK vALvn.

Be it known that we, Gnr1-ms V. Frrn and .Hiannr K. Banwicn, J11, citizens of the 'United fitates residing at Charlotte in the county of Mccklenburg, State of North Carolina, have invented a new and useful Combination-Lock Valve, of which the fol- This inventionrelates to a valve especially designed tor use in controlling the supply of gasolene tothe carbureter of a hydrocarbon motor such as used in automoblles,

motor boats, motorcycles'and the like.

One of the objects of the invention is to provid a valve made up of relatively movable sections constituting tumblers of a combination lock the said sections or tumblers having cooperating means whereby, by the manipulation of a knob or stem openings within the tumblers or sections will. be brought into register and thus permit the passage of liquid through the valve from the inlet to the outlet. When, however, any one of these tumblers is out of registration, the passage of liquid through the valve will be cut off and can only be effected by manipulating the device to bring the various'tumblers into a predetermined relation; lVith the foregoing and other objects in view which will appear the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed,-it being understood that changes in the precise embodiment of the invention herein disclosed can. be made within the scope of what is claimed, with out departing from the spirit of the invention.

In the accompanying drawing, the preferredform of the invention has been shown; In said drawing :Figure 1 is a central vertical section through the valve, the tumblers being shown in position to permit the passage of fluid through the valve. Fig. 2 is a face view of the valve operating knob and the dial plate adjacent thereto. Fig. 3

is a section on line AB Fig. 1. Fig. 4: is a section on line G-D Fig. 1.

Referring to the figures by characters of reference 1 designates a cylindrical casing provided in one end with an outlet port 2 and adjacent its other end with an inlet port '3. A valve stem 4 is mounted for rotation within the casing and may be rotated in any suitable manner, as by means of a knob 5,

there being a dial 6 adjacentthe knob'having any desired arrangement of characters thereon to guide the user in manipulating the valve.

The casing 1 is concentric with the stem and fitting snugly within the casing is a series of tumblers 7 and 8, each of these tumblers being in the form of a disk pro vided in its periphery with recesses 9. Each recess has a shoe 1O movably mounted therein and normally pressed against the inner surface of the wall of the casing '1 by a spring 11. These shoes by frictionally engaging the wall of the casing serve to retard the'rotation of thetumblers within the casing.

The lowermost tumbler 7 is formed with recesses 12 adapted to receive the ends of a pin 13 extending through one end portion of the stem 4 so that, when the stem is rotated, the tumbler 7 will be likewise rotated. Thistumbler has a circular series of recesses 15 in one face any one of which is adapted to receive a pin 16. Said pin projects into a circular groove 17 formed in the adjacent face of the next adjoining tumbler S and the inner wall of this circular groove has a pin 18 projecting therefrom and adapted tov engage the pin 16 during the relative movement of the two tumblers '7 and 8.

Formed in that face of the tumbler 8 re mote from the groove 17 is a circular series of recesses 19 any one of which is adapted to receive a pin 20 similar to the pin 18 and which projects into the groove 17 of the next adjoining tumbler 8. The uppermost tumbler 8 is not provided with a pin 20 but is, instead, engaged by one end of a coiled spring 21 which is mounted on the stem 4 and bears against the end of the casing 1.

This spring 21. serves to hold several tum-' hlerspressed tighty together. The port 3 enters into the casing 1 between the innermost tumbler 8 and the-adjacent end of the casing 1.

Each of the tumblers 7 and 8 has an opening 22 extending entirely through it and these openings are all so located that when the various tumblers are brought to predetermined positions relative to each other the openings '22 in the different tumblers will register with each other and with the outlet port 2, thus establishing communication between the ports 2 and 3.

It will be apparent that by connecting a supply tank or reservoir to the port 3 and by extending a iced pipe from the port 2 to the carburc or other point of consumptiou the comma iication between the supply and the port can be cut oil simply by turnbig one or umre of the tumblers 7 and 8 by means-oi the] i n Before the fuel nan be permitted to n to the port 55, it will be necessary to so manipulate the tuinliilers by means of the stem l, to bring the differ but open igs' into register with each other and with "he port 2.

Li lie de ice constituting the present invention is rel v simple, durable and efiicient and by reason of its compact construction, can be readily laced in position upon a motorcjrlm-auto .obi e or the like.
